Why the buffer is 0 when I play the "rtsp" movie from the internet? I wrote a appliaction to play the movie from the internet.I try many times and could not found out the reason ,so I decided to have a look at opencore source code. I look at the opencore source code ,and I find that it is the most important code is below.But I could not find out how the percentage is increasing .So I could not find out where the reason caused all these.could someone give me a hand? —————————————————————————————————————— void PlayerDriver::HandleInformationalEvent(const PVAsyncInformationalEvent& aEvent) { ...... case PVMFInfoBufferingStatus: { const void *buffer = aEvent.GetLocalBuffer(); const size_t size = aEvent.GetLocalBufferSize(); int percentage; if (GetBufferingPercentage(buffer, size, &percentage)) {
//This place print the log "D/PlayerDriver( 31): buffering (0)" LOGD("buffering (%d)", percentage); mPvPlayer->sendEvent(MEDIA_BUFFERING_UPDATE, percentage); } } break; ...... ----------------------------------------------------------------------------------------------------- bool GetBufferingPercentage(const void *buffer, const size_t size, int *percentage) { if (buffer == NULL) { LOGI(" GetBufferingPercentage Invalid buffer: NULL"); LOGE("Invalid buffer: NULL"); return false; } if (sizeof(int) != size) { LOGE("Invalid percentage buffer size %d (expected %d)", size, sizeof(int)); return false; } // TODO: The PVEvent class should expose a memcopy method // that does bound checking instead of having clients reaching // for its internal buffer. // Clamp the value and complain loudly. oscl_memcpy(percentage, buffer, sizeof(int)); if (*percentage < 0 || *percentage > 100) { LOGE("Invalid percentage value %d", *percentage); return false; } return true; } ____________________________________________________________- log D/PlayerDriver( 31): buffering (0) D/PlayerDriver( 31): buffering (0) D/PlayerDriver( 31): buffering (0) D/PlayerDriver( 31): buffering (0) D/PlayerDriver( 31): buffering (0) D/PlayerDriver( 31): buffering (0) D/PlayerDriver( 31): buffering (0) D/PlayerDriver( 31): buffering (0) D/PlayerDriver( 31): buffering (0) D/PlayerDriver( 31): buffering (0) D/PlayerDriver( 31): buffering (0) while play the "http" movie ,it's ok; and now I don't konw where the percentage is not increasing ,and how the percentage is increasing. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
